COMPOSITION FOR PAINTING IRON, WOOD, &o.

No Drawing.

To all whom it may concern.

Be it known that I, GnneoRY loooMNorr,

a subject of the Emperor of Russia and a resident of Alatyr, Russia,have invented certain new and useful Improvements in Compositions forPainting Tron, Wood, &c., of which the following is a specification.

The green paint ordinarily employed con sists largely of high-grademineral green, which is comparatively very costly, and has a corrosiveeffect on iron The improved paint is far cheaper and, at the same time,more brilliant and durable than this mineral green, and has no corrosiveeffect on iron. For painting iron, wood, etc., both a ground or bodypaint and a finishing paint are employed, as usual. The composition andthe method of preparing both these paints are substantially similar, thedifference between them being the addition, to the finishing paint, ofcertain substances, which are not necessary in the ground or body paint.

In preparing the ground or body paint, sulfate of copper is diluted,together with ordinary hard soap, in water, and the mixture then boiledin a copper or enameled vessel until a homogeneous mixture of sulfate ofcopper and soap is formed on the surface of the water. The mixture ofcopper salt and soap thus obtained is carefully separated by decantationfrom the water and from the various impurities contained in the soap,which impurities settle on the bottom of the kettle during boiling; andafter the said mixture has cooled, it is twice washed in pure, coldwater. The washed mass is then diluted with ordinary boiled hempseed orother vegetable oil, to which a small quantity of powdered Prussian blueor ultramarine pigment is added. The mass thus prepared is next heatedto boiling temperature, and to it, while boiling, are added powderedbarium sulfatei. e.,heavy spar, white lead and chalk, the mass beingcarefully mixed continuously. After boiling, a sufficient quantity ofwater is poured into the vessel, and the mass carefully washed in it.The washed mass is carefully rubbed on ordinary rubbing desks or tablessuch as used in preparing mineral paints, the mass Specification ofLetters Patent.

thus obtained constituting the new ground or body paint. This mass maybe diluted, for use, with any desired quantity of boiled vegetable oil.

For preparing the finishing paint, a mix ture of sulfate of copper isboiled with hard soap in water until a homogeneous mixture is formed onthe surface. This mixture is removed, as before; washed in pure coldwater two or more times, and then diluted with boiled hempseed or othervegetable oil, to which a small quantity of Prussian blue or ultramarinepigment and an appropriate quantity of powdered mineral green pigmentare added. The mixture obtained is then heated to boiling temperature;and to it, while boiling, are added powdered barium sulfate,. 6., heavyspar,-white lead and cantation, or otherwise, and finally is rubbed onrubbing tables. This finishing paint is also diluted for use with anydesired quantity of boiled vegetable oil.

The proportions of the materials employed may vary within certainlimits; but the following proportions give the best results: I
